Patent DE-2720948-A1 (DE)
Title: One way detent for adjusting hospital bed - has lock plate with apertures to limit range of adjustment
Inventor: SVENSSON LARS IVAR
IPC: A61G7/10
Filed: 1977-05-10
Abstract: The one-way detent mechanism, for adjusting the position of a hospital bed has a rod (1) engaged by an aperture in a transporter plate (13). When a link (17) connected to the plate is pulled the plate is tilted to grip and thus move the rod outwards. A locking plate (10) engaging the rod allows outward but opposes inward movement of the rod. At the end of the outward motion of the rod a stop (37) connected to the rod reverses the locking plate to lock the rod against outward movement. Pushing of the link places the locking plate int a neutral position and frees the rod for inward movement.

Title: Vehicle axle drive differential housing mfr. - has heated aluminium tube placed in die and expanded locally under large internal hydraulic pressure
Inventor: VOIGTLAENDER OTTO DR ING
IPC: B21D53/90
Filed: 1978-04-18
Abstract: An aluminium tube is positioned in a forming die, which can be preheated, and is then subjected to a high internal pressure from both ends (7 and 4) using hydraulic oil or an inert gas. This forces the tube outwards to take up the form of the differential housing, leaving only the mouth of the propellor shaft tube and the entry for the differential gearing to be machined. The tube used, is of a slightly smaller dia. than the final dimension, thus absorbing an even overall stress. The higher cost of using aluminium is offset by the elimination of weeding necessary when joining the two halves of a conventionally produced still pressed housing.
Patent DE-2816997-A1 (DE)
Title: Multiple radiation source - with inclined mounting faces on positioning base plate in box
Inventor: KLOTZ ERHARD
IPC: H05G1/04
Filed: 1978-04-19
Abstract: A multiple source of radiation, e.g. X-rays for the prodn. of coded super-position images, consists of a box with a bottom plate which carries a positioning base plate. The base plate contains inclined faces for the radiation source mounts of different angles which depend on the position in space and cause all sources to be directed to the same focus, although their vertical distances are equal. This greatly simplifies the assembly of the multiple source of radiation. The individual sources are fitted outside to their mounts and these are simply erected on or coupled to the inclined faces.

Title: Motor vehicle gas turbine arrangement - includes Rankine turbine driving turbocompressor and Brayton turbine with exhaust heating intermediate heat exchanger
Inventor: EARNEST ERNEST ROBERT
IPC: F01K23/10
Filed: 1978-07-06
Abstract: Combustion air is delivered by a compressor (14) to a combustion chamber (18) which also receives fuel. The hot gases drive an open circuit turine (20) which drives the output shaft (21). The exhaust gases pass through a heat exchanger (22) in which they evaporate an organic working fluid which drives a closed Rankine cycle turbine (26). This turbine is directly coupled to the compressor (14) which it drives. The exhaust from the Rankine turbine is condensed in a preheater (44) and an air cooled condenser (46). The fan (38) for the condenser is driven through a gearbox (30) to return the condensate to the evaporator. The combined cycle results in a gas turbine with good acceleration for vehicle use.
